Generators

Permanent Magnet (PM) generators from Comprehensive Power (CPI) are the choice for many renewable energy applications, including wind, wave, and tidal power, for converting energy to electricity. Comprehensive Power designs and builds high performance PM generators capable of harvesting the maximum amount of energy in a system with reliability, limited maintenance requirements, high power with small size and light weight designs, and the ability to operate with high efficiency across a large range of speeds.

A PM Generator from Comprehensive Power

Our innovative designs provide high power density, enabling our generators to commonly be deployed in direct drive configurations, which eliminate the unnecessary cost, complexity, size, and weight required by cumbersome gear and transmission systems.

Comprehensive Power generators are self-exciting, removing the need for external power. And, when connected to an energy source such as a utility grid or battery bank, a Comprehensive Power generator can even act as a motor to spin a turbine during startup, if needed. The power range of our generators spans from a few kilowatts to several megawatts, and from rated power at 10 to thousands of RPMs. The electrical performance can be optimized based upon requirements.

Variable Speed Generation (VSG)

Comprehensive Power Permanent Magnet (PM) Generators are also utilized within variable speed generation (VSG) configurations, typically consisting of multiple diesel engines, a Comprehensive Power TeraTorq® PM generator for each engine, and TIM modules drive and control electronics. This system architecture provides operators with several benefits including:

 

Features

Benefits

Reduce fuel consumption. Rather than operating diesel engines continuously at full speed, engine speed is automatically adjusted based upon actual system power requirements.
Reduced emissions. Tests with Comprehensive Power PM Generators have shown significantly reduced emissions of HydroCarbons, Nitrous Oxide, Carbon Dioxide, and other particulates during diesel engine operation.
Reduced Noise. Engines operating at reduced speeds are quieter. In addition to the safety benefits of lower noise, certain field activities (such as drilling) may be able to be located closer to populated areas due to quieter operations.
Reduced engine wear. Your engines will last longer. VSG operation shields engines from torque transients, which cause engine thermal fatigue, stress, and mechanical resonance.
System flexibility, redundancy, and safety are all enhanced. Engines no longer are required to be synchronized and multiple engine types can utilized.Power is still supplied to all system components even if an engine fails or is taken off line for servicing.
